Background: Most studies of risk factors for alcohol-related problems have focused on biological family history as a primary risk factor. However, other factors, such as early-age heavy drinking, are also risk factors for sustained or progressive heavy consumption. Little is currently known about the mechanisms underlying binge or heavy drinking.Methods: This study examined the acute subjective and objective effects of ethanol in heavy drinkers versus light drinkers. Thirty-four subjects participated in this within-subjects study consisting of three early-evening testing sessions in which subjects consumed a beverage containing either 0.8 or 0.4 g/kg ethanol or placebo.Results: Compared with lighter drinkers, heavy drinkers were more sensitive to the positive stimulantlike effects of ethanol (p Ͻ 0.05), especially during the increasing limb of the blood alcohol curve. Heavy drinkers also showed less sedation and cortisol response after alcohol than the light drinkers (p Ͻ 0.05). Conclusions:The results indicate that young adult binge drinkers show a biphasic alcohol response, with heightened sensitivity to stimulant-like alcohol effects and greater tolerance to sedative alcohol effects compared with their light-drinking counterparts.Key Words: Alcohol Response, Heavy Drinker, Risk for Alcoholism, Biphasic Alcohol Effects Scale, Cortisol. H EAVY ETHANOL DRINKING among young adultsis a serious problem in this country (Chou and Pickering, 1992), and the consequences of this excessive use, both financial and personal, are widespread. The cost of ethanol-related health care, loss of productivity, crime, and accidents totals more than $148 million annually in the United States alone (Harwood et al., 1999). Approximately 30% of all accidents are connected to ethanol use, and excessive ethanol use contributes to many chronic and life-threatening illnesses, including gastrointestinal, liver, and cardiovascular disease ("Tenth Special Report to Congress on Alcohol and Health," 2000). Data indicate that those who start drinking before the age of 14 years are 12 times more likely to be injured in accidents while under the influence of ethanol than those who start drinking after age 21 (Hingson et al., 2000). Early-onset alcohol drinking is also strongly associated with lifetime alcohol problems (Chou and Pickering, 1992). Understanding the factors that contribute to the escalation and maintenance of excessive ethanol drinking is crucial to improve prevention, public education, and early intervention strategies. At this time, it is still unclear why some individuals abuse ethanol and others do not.One potential source of vulnerability to developing alcohol use problems is the quality and magnitude of acute subjective responses to alcohol (Fischman and Foltin, 1991). For instance, individuals who experience greater stimulant-like effects from an acute dose of ethanol also report greater drug liking and euphoria and have greater behavioral preference for ethanol (over placebo) compared with those individuals who experience mos...

This study evaluated whether there were increasing admissions for illicit drug abuse treatment among older persons from 1992 to 2005 in the United States and describes the characteristics, number, and type of substances most commonly abused in this population over this 14-year period. Analyses used public data files from the Treatment Episode Data Set, which tracks federally and state funded substance abuse treatment admissions. From 1992 to 2005, admissions for illicit drug abuse increased significantly; in 2005, 61% of admissions age 50 to 54 years old and 45% of admissions age 55 years and older reported some type of illicit drug abuse, most commonly heroin or cocaine abuse. Criminal justice referrals for drug abuse admissions have increased over time and daily substance use remains high. Efforts to determine best practices for prevention, identification, and treatment of illicit drug abuse in older persons are indicated.

The current study examines the longitudinal relationship between anxiety disorders in general, specific phobia in particular, and subsequent-onset alcohol use disorders in an adult population-based sample. In addition, we explore whether the hypothesized associations vary by gender. Approximately 23 years of data from the Baltimore ECA (Epidemiological Catchment Area) Follow-up (N=587) allow for the estimation of the development of incident alcohol use disorders in later life among those with anxiety disorders at the time of the baseline interview in 1981. Though baseline specific phobias were common, neither number of, nor any specific fear was statistically associated with the onset of alcohol use disorders. Rather, the findings suggested a modest association between adult sub-clinical specific phobia (without substantial distress or interference) and later-onset alcohol use disorders (OR=3.2). Moreover, we find that this association might be stronger for women than for men.
